You don't need to run ID 5 times to get 5 different pieces of data from it. Run it once, get all the data from it the first time.

You are using single quotes, which take their contents literally, where you need backticks, which run their contents. But you don't even need that statement.

You don't need to do \( all the time, just use quotes. Variables will expand inside double-quotes, even, so you don't need to end the quotes to use a variable.

Whenever you're doing if [ `... | wc -l` -gt somevalue ] to check something, you've probably missed a simpler way. Here, since I've overwritten the $1 ... arguments, I use the special "$#" variable, the number of arguments instead.

Code:

        USUARIO=$1
        DATA=`id $USARIO 2>/dev/null` # Save the data, ignore the error strings
	if [ $? -ne 0 ]
	then
		echo "El usuario $USUARIO no existe"
		exit
	fi

        # Note that $DATA is not in quotes and MUST NOT be in quotes.
        set -- $DATA # $1=NOMBRE, $2=GRUPOID, $3=GRUPOID2, etc.

	echo "(UID) y nombre: $1"
	echo "(GID) y numero de goup1: $2"
        [ "$#" -gt 2 ] && echo "(GID2) y numero de group2: $3"
